CONTAINER STRUCTURE Filed July 11, 1930 Patented July 28, 1931 PATENT OFFICE ms A. Because, or vAN wnnr, orno comramnn srnuc'r'cnn Application filed July 11, 1930. Serial No. 467,205.

My invention relates .to container structures. It has to do particularly with the provision of a novel type of end closure'in con- ;junction with a means for securing such end 1 .closure in position upon the body portion of the container. p

In the past, devices of this type have involved unnecessary complication of structure. This has been true of the closure itself but has been especially true of the means for securing 1 this closure in position upon the container. Various types of securing means have been provided and many of these have-been so constructed 'or of -such a fragile nature as to be readily'mutilated or distorted in shipment or handling that their utility has been impaired. j a

One of the objects of my invention is to provide a closure for the end of a container of'simple form but which is of rugged structure and capable of resisting heavy strains or shocks which inevitably arise in handling,

articularly where'the container is utilized or the shipment ofcomparatively heavy ma-' terial.

Another object of my invention is to provide a closure. for a container and a securing means therefor, with both of these elements so constructed and related that they may be brought into proper cooperative relation with maximum ease, and when in such relation, maybe adequately'locked against separation with a minimum of difiiculty.

Another object of myinventio'n is to pro- 33 vide a; closure for agcontain'er and a securing means-therefor, which securing means is of such construction that the closure may be sealed in positionupon the container with a um ofdiflic'ult'y and in, such a manner 7 40 "that the "maintenance of the closure upon the container 'will'impose no strains upon the sealingmeanskf p Thepreferr'ed-embodiment'of my inven- I "tion contem lates the'provision of a contain- I 5 er closure w 'ch is adapted to for application to the tubular body'portion of.v a container of fiber board 'strawboard or pulp board. Zlhis closure is preferably formed in one 3 piece with a" circular body portion and with an annular flange which is connected to the circular body portion by a grooved formation designed to receive the end of the tubular body portion of the container in such a way as to effect a cooperative bracing action. The circular body portion of the closure is preferably provided with reenforcing ribs to increase the strength thereof.

In this preferred form of my invention, the means for securing the closure in position upon the end of the container comprises a m plurality of substantially flat metallic strips vertically secured to. the exterior wall of the container at several places throughout the circumference thereof. Each of these metallic strips has its upper extremity 'unse- 5 cured and bent outwardly so that it is slightly spaced from the container wall. The closure is provided in its flange with an opening for the reception of each of the securing elements and each opening is so designed that it will readily receive the upperextremity of a securing element when the closure is placed in position upon the container. Further more, the cooperative securing elements of my device are so designed that they provide convenient apertures for a sealing wire and at the same time protect the sealing wire from any strain due 'to any tendency of the closure to separate from the container.

The preferred. .embodiment of m invention is shown in the accompanying rawings wherein similar characters of referencedesignate corresponding parts andwherein:

Figure 1 is a perspective view of a con tainer with my end closuresapplied thereto.

Figure 2 is a section taken through an upper corner of my container with my end closure thereon. Y

figure 3 is avertical sectional view taken through one of my end closures.

Figure 4 is a top plan view of the structure shown in Figure 1.

In the drawings, I have shown a- 'container' comprising a body portion 1 This body '9 portion is preferably of tubular form and open at both ends, these ends being designed to be closed by a metallic member.

Disposed at spaced ingrvals about the tubular body portion 1 are ring means-which may be generally designated 2. Each secur- 'ing means is preferably formed from a flat strip of metal with a plurality of prongs stamped inwardly therefrom as indicated at '3, 4 and 5. Intermediate the prongs 4 and 5,each metallic strip is preferably provided with a rib 6. When applied to the container, the prongs 3, 4 and 5 are passed through the wall thereof and then bent sufficiently to clinch the securing strip firmly to the container wall.

rality of annular ribs 10. It is also provided with a plurality of radial ribs 12.-

These annularand radial ribs are preferably stamped in the disk-like portion.

The disk-like portion 8 is connected to the flange 9 of the closure by means of an upwardly bent annular section 13 which cooperates with the annular flange 9 to form a groove 14 of annular form which is designed to receive and closely embrace the end of the tubular body portion'of the container.

The lower end of the flange 9 of the clo sure is bent as at 15 to completely enclose a wire 16.. At spaced intervals 'around the flange 9. openings 17 are provided in this flange; These openings are preferably produced by stamping and the stamping action is such that the upper wall 18 of each opening is bent inwardly so that it lies close to the outer surface of the container body portion 1. In fact, it preferably lies closer to this outer surface than the remainder of the flange 9. It will also be noted that the lower wall 19 of each opening 17 is bent outwardly awayfrom the (outer surface of the body portion 1 of the container and this is also preferably true of the bead 15.

From this structure, it will be obvious that the placing of an end closure upon the body portion of the container with its 0 ening 17 m proper alignment with the securmg strips 2 and the forcing of this container firmly intov position upon the body portion will cause the wall 18 of each opening to wedge into position beneath the upper extremity 8 of each strip. The wall 19 of'each opening and. the bead-15 immediately therebeneath,

being spaced from the container wall- Will'- pass on the outside of the extremity of the strip and this extremity will then be in such position that it may be readily bent'over, as are the fasteners shown, in connection with the bottom closure in Figure 1. When these.

strips are thus bent, the closures will be firmly retained in position against all possibility of accidental removal.

When the closure is once in position, a sealsealing means, while this securing means is so designed as to permit the ready application of a sealing means which will not be liable to breakage due to any tendency of the closure to separate from the container.

It will be seen that I have provided an unusually simple structure which is, nevertheless, readily assembled and which, when assembled, produces a container with a rigid end formation with the container and the closures bracing each other and well calculated to resist any strains or shocks to which they are likely to be subjected. Furthermore, it will be noted that thesecuring means for the container closure does not project into a position where it is liable to become distorted or bent either before or after app cation of the closure. Nevertheless each of these securing devices is in such position that the application of the container closure to the container will automatically position these securing devices in such relation tothe container closure that they need only be bent to effect a rigid locking of the closure upon the body portion of the container.

Having thus described my invention, what I claim is:

and a substantially vertical annular flange designed to embrace said body portion and lie in contact'with and in substantial arallelism thereto, said annular flange having an opening formed therein with its upper edge closely adjacent the outer surface of said body portion and its lower edge spaced from said body portion, and a securing means carried by said body portion and having an upstanding leg which is bent outwardly to such an extent that it will ride over said firstnamed edge and under said second named edge when said cover is applied.

2. A container structure comprising a body portion, an upstanding securing means mounted 'on the outer surface of said'body portion and having its upper end initially divergent from the plane of surface on which said securing means is mounted, a closure having a disk-like portion and a substantially vertical annular flange designed-to embrace said body portion and lie in contact with and in substantial parallelism thereto, said annuat such an angle that the placing of the closure on the container and downward movement of the closure with such opening in alignment with said securing means will cause the lower wall of the opening to pass on the outside and the upper wa of the opening to pass on the inside of said securing means.

3. A container structure comprising a body portion, an upstanding securing means mounted on the outer surface ofsaid body portion and having its upper end initially divergent from the plane of surface on which said securing means is mounted, said securing means terminating within the height of said body portionfii closure having a disk-like portion and a substantially vertical annular flange designed to embrace said body portion and lie in contact with and in substantial parallelism thereto, said annular flange having an opening formed therein at such an angle that the placing of the clo sure on the container and downward movement of the closure with such opening in alignment with said securing means will cause the lower wall of the opening to pass on the outside and the upper wall of the opening pass on the inside of said securing means.

4; A container structure comprising a body portion, a securing means on said body portion embodying a flat strip secured to the outer surface of said body. portion and having an outwardly bent portion intermediate its length for the reception of a sealing wire, a closure for one end of said body portion,

and a sealing means, said securing means being constructed-to maintain'said closure upon said body. portion without imposing any strain upon said sealing means.
